Problems solved by technology

[0005] However, how to device such a nanoparticle solution has encountered a series of difficulties in the process of deviceization, for example, the polymer carrier has poor wrapping performance on the probe molecules, and the probe molecules are easily separated from the polymer carrier. Migrate out, so the stability of the nanoparticles cannot be guaranteed

Abstract

The invention discloses a formaldehyde detection film sticker and a using method thereof. Formaldehyde probe molecules are loaded and wrapped with a ternary photo-crosslinkable random copolymer P (St-co-VM-co-AMPS), and photo-crosslinkable polymer nanoparticles loaded with formaldehyde probe molecules are prepared. The nanoparticles are cross-linked by ultraviolet irradiation, the probe molecules are immobilized, and the stability of the probe molecules is enhanced, and the nanoparticle solution is printed on the filter paper at a certain pH and temperature by inkjet printing technology to form a coating. Layer to get formaldehyde detection test paper; then paste pressure-sensitive adhesive on one side, and then compound release paper to get formaldehyde detection film sticker, just tear off the release paper when using, which is very convenient.

Description

technical field [0001] The invention belongs to the field of polymer materials and environmental detection, and in particular relates to a formaldehyde detection film sticker and a use method thereof. Background technique [0002] Formaldehyde is irritating and suffocating at room temperature. It is a colorless gas that is extremely harmful to human body. [0003] In recent years, with the advancement of chemical detection and analysis technology, the rapid detection of formaldehyde has also been developed rapidly. Formaldehyde test paper is a commonly used detection method, but the test paper has a short storage period due to the easy migration of probe molecules. [0004] Patent CN103819693A reports a method for preparing formaldehyde-sensitive nanoparticles, specifically using polymer P (St-alt-Man) as a carrier, and wrapping the formaldehyde detection probe in the polymer carrier to solve the instability of small molecule probes problem. [0005] However, how to device...
